Fail to run simple script about dgsh HOT 4 CLOSED

On Linux it works.
On Mac the shell reports a SIGPIPE after the negotiation procedure has completed successfully, but that's only part of the problem:

sgsh -c 'echo hi | sed s/^/a/'

still outputs nothing although the script completes successfully.
I notice a couple of differences in the way sgsh behaves on these two platforms.
I'll try to sort it out.

from dgsh.

For me it fails on stereo.

from dgsh.

I'm on stereo too.
I also located your script and used that; still successful.

/usr/local/sgsh/bin/bash --sgsh /.../simple 2>err

I notice the way you call sgsh and at first I thought it was a shorthand, but if not that's perhaps the reason.

from dgsh.

Excellent, both work fine. I thought sgsh was a shorthand for bash --sgsh.

[dds@stereo sgsh]$ bash --sgsh simple 2>/dev/null
ahi
bthere
[dds@stereo sgsh]$ bash --sgsh -c '{{ echo hi & echo there & }} | {{ sed s/^/a/ & sed s/^/b/ & }}' 2>/dev/null
bthere
ahi

from dgsh.
